1. Low/Slow Production:
a) Low Incoming Water Pressure: Assure a minimum of 40 PSI of incoming water pressure. Premier offers a booster pump if home water pressure is too low.  Make sure water supply is turned on and Adapt-a-Valve is fully open.
b) Crimps in tubing: Check tubing and straighten or replace as necessary.
c) Clogged pre-filters: Replace pre-filters (Typically every 6 months).
d) Fouled membrane: Replace the RO membrane (Typically every 2 to 4 years).
 
2. Milky Colored Water:
a) Air in system: Air in the system is a normal occurrence with initial start up of the RO system. This milky look will disappear during normal use within 1 to 2 weeks.  If condition reoccurs after a filter change, drain the storage tank 1 to 2 times.
 
3. System Constantly Running and Will Not Shut Off:
a) Low Incoming Water Pressure: Assure a minimum of 40 PSI of incoming water pressure.  Premier offers a booster pump if home water pressure is too low.  Make sure water supply is turned on and Adapt-a-Valve is fully open.
b) Crimps in tubing: Check tubing and straighten or replace as necessary.
c) High water pressure: Check incoming water pressure to make sure it does not exceed 80 psi.  A pressure regulator valve may be necessary (Available at the online store).
d) High/Low pressure in Tank: Empty storage tank of water. Using a bicycle pump or a small compressor set the storage tank air pressure to 5-7 psi. Use a Digital Air Gauge for best results.
 
4.  Noise / Water From RO Faucet Air-Gap Hole Or Noise From Drain:
Note: A gurgling sound from the air-gap/drain may be heard during the regeneration cycle.
a) Crimp in the Black 3/8” drain tube: Check the black 3/8” drain tubing to make sure it is as short and straight as possible between the RO faucet and the drain saddle.  The tube must go in a downward direction with no kinks or loops.  
b) Restriction in the Black 3/8” drain tube:  Disconnect the black 3/8” tubing from the drain saddle under the sink. Using a straightened wire coat hanger or equivalent metal wire, snake out the tubing to clear out the restriction.
 
5. Small Amount Of RO Water In The Storage Tank:
a) System starting up: Typically it will take 3-6 hours to fill the RO tank.  
Note: Low incoming water pressure and/or temperature can drastically reduce production rate.
b) High/Low pressure in Tank: Empty storage tank of water. Set tank air pressure between 5-7 psi. Use a Digital Air Gauge for best results.
c) Clogged pre-filters: Replace pre-filters.
d) Fouled membrane: Replace the RO membrane.  (Typically will last 2-4 years).

This can be caused by the air gap faucet, the location of the drain saddle, a restriction in the drain tube, or water pressure in excess of 85 psi.
Some noise is caused on start-up or after filter changes by air being purged from the system. Once the air is expelled from the unit (usually after about 5 minutes) this noise should subside.
Although the air-gap faucet inherently makes some noise, this can be amplified if the water running from the drain saddle splashes into the water in the sink trap. This noise can be reduced by either moving the drain saddle to a greater height, or by securing a fishing line through the drain saddle and down into the sink trap, allowing the water to run down the side of the drain pipe.
A restriction in the drain tube can be caused by debris from the dishwasher or garbage disposal. The tube can be unclogged by removing it and cleaning it with a wire or coathanger.
If the water pressure is above 85 psi, a pressure regulator may be required.
 
Faucet Leaks From Air Gap
 
This can be caused by a crimp in the drain line, a restriction in the drain line, or a clogged drain tube.
If there is a crimp in the drain line, check and straighten out the tubing.
If the drain line is not straight, it can cause leakage from the faucet. Remove the drain line, check for blockage (which can be removed with a coat hanger) and make sure the connection between the drain and drain saddle is as short and straight as possible. The drain line can be trimmed if there are any dips or loops where water might settle.
The drain line can also become clogged by the dishwasher, garbage disposal, or even the impurities removed by the RO unit. To fix this, disconnect the line and clean it out with a wire before re-connecting.
 
Minimal Water In Storage Tank
 
This can be caused by system start-up, low water pressure, excessive air in the water tank bladder, or a faulty check valve.
If the system is just starting, wait 6-10 hours for the tank to fill. Low water temperatures and pressures can also reduce the production rate.
If the water pressure is below 40 psi, a booster pump may be necessary. These are available from us either online or by calling 1-800-752-5582.
Excessive air in the tank bladder or air cushion can squeeze the space designed for the water. Using a tire pressure gauge, check to see that the pressure is between 5 and 7 psi (tank should be free of any water). If the pressure is higher, bleed the tank air until it is at the 5 and 7 psi pressure level. This test should only be done when the tank is empty.
A faulty check valve can also cause a small amount of water in the tank. To check this, do not use any water from the RO unit for 24 hours, then check the water flow to the drain in the morning before any water flows through the house. If the water is still draining, consult us at 1-800-752-5582.Faucet Leaks From Air Gap

Water Tastes Or Smells Funny
 
This can be caused by clogged prefilters, fouled membranes, or a failure to annually sanitize the unit.
If the prefilters are clogged, replace the prefilters after washing the inside of all the housings out with a mild detergent and rinsing them out with RO water, if possible.
If you think the membrane may be fouled, have the water tested, and if the membrane is fouled, then replace it after cleaning the membrane housing with a mild detergent and rinsing it out.
If you have not sanitized your system in the past year, follow the procedure at the bottom of the page.
 

Leaks From Unit Or Filter Bowls
 
Leaks can be caused by loose fittings, a missing, damaged, or improperly seated O-Ring, or an improperly inserted plastic ferrule on the brass fitting.
If the fittings are not tightened, then carefully re-tighten the fittings.
If the O-ring is missing or damaged then contact a dealer or Premier for a replacement.
If the O-Ring is out of round, make sure the O-Ring is properly lubricated and inserted into its housing before replacing the housing.
If the plastic ferrules are inserted backwards, remove and re-orient them, making sure the tapered end points toward the valve.
